What is a load estimate?

• A precise calculation using detailed inputs
• An approximation based on methods like rules of thumb or quick assumptions
• A finalized load analysis
• None of these

How is a load calculation different from a load estimate?

• It only uses assumptions instead of actual data.
• It is less detailed than a load estimate.
• It involves detailed analysis and is often performed using computer software.
• All of these

Why is the term “estimate” still appropriate for the results of a load calculation?

• The calculation is always inaccurate
• The calculation is based on guesses
• Not all input details required by the software are known, requiring user judgment
• None of these

Which of the following is NOT a characteristic of a load estimate?

• Use of quick hand calculations
• Based on assumptions
• Reliance on check figures
• All of these

What tools are commonly used today for detailed load calculations?

• Rules of thumb
• Check figures
• Computer software and spreadsheets
• Quick hand calculations

What is the Cooling Load used for?

• Determining the building's structural strength
• Estimating the electricity usage of a building
• Selecting the air conditioning equipment
• Measuring the indoor air quality

What is the purpose of the Heating Load evaluation?

• To estimate heat generation within a space
• To select the heating equipment
• To measure indoor air temperature
• To improve air conditioning efficiency

Which of the following is NOT a factor in Cooling Load estimation?

• Heat coming from outdoors
• Heat generated within the space
• Heat on a design day
• All of these

Source of heat is outside the conditioned space:

• External loads
• Internal loads
• System loads
• None of these

Source of heat is within the conditioned space:

• External loads
• Internal loads
• System loads
• None of these
